This happens through a number of hardware capability structs - * described below. - * - * The fundamental structure for each device is the 'wiphy', of which each - * instance describes a physical wireless device connected to the system. Each - * such wiphy can have zero, one, or many virtual interfaces associated with - * it, which need to be identified as such by pointing the network interface's - * @ieee80211_ptr pointer to a &struct wireless_dev which further describes - * the wireless part of the interface, normally this struct is embedded in the - * network interface's private data area. Drivers can optionally allow creating - * or destroying virtual interfaces on the fly, but without at least one or the - * ability to create some the wireless device isn't useful. - * - * Each wiphy structure contains device capability information, and also has - * a pointer to the various operations the driver offers. The definitions and - * structures here describe these capabilities in detail. - */ - -/* - * wireless hardware capability structures - */ - -/** - * enum ieee80211_band - supported frequency bands - * - * The bands are assigned this way because the supported - * bitrates differ in these bands. - * - * @IEEE80211_BAND_2GHZ: 2.4GHz ISM band - * @IEEE80211_BAND_5GHZ: around 5GHz band (4.9-5.7) - * @IEEE80211_NUM_BANDS: number of defined bands - */ -enum ieee80211_band { - IEEE80211_BAND_2GHZ = NL80211_BAND_2GHZ, - IEEE80211_BAND_5GHZ = NL80211_BAND_5GHZ, - - /* keep last */ - IEEE80211_NUM_BANDS -}; - -/** - * enum ieee80211_channel_flags - channel flags - * - * Channel flags set by the regulatory control code. - * - * @IEEE80211_CHAN_DISABLED: This channel is disabled. - * @IEEE80211_CHAN_PASSIVE_SCAN: Only passive scanning is permitted - * on this channel. - * @IEEE80211_CHAN_NO_IBSS: IBSS is not allowed on this channel. - * @IEEE80211_CHAN_RADAR: Radar detection is required on this channel. - * @IEEE80211_CHAN_NO_HT40PLUS: extension channel above this channel - * is not permitted. - * @IEEE80211_CHAN_NO_HT40MINUS: extension channel below this channel - * is not permitted. - */ -enum ieee80211_channel_flags { - IEEE80211_CHAN_DISABLED = 1<<0, - IEEE80211_CHAN_PASSIVE_SCAN = 1<<1, - IEEE80211_CHAN_NO_IBSS = 1<<2, - IEEE80211_CHAN_RADAR = 1<<3, - IEEE80211_CHAN_NO_HT40PLUS = 1<<4, - IEEE80211_CHAN_NO_HT40MINUS = 1<<5, -}; - -#define IEEE80211_CHAN_NO_HT40 \ - (IEEE80211_CHAN_NO_HT40PLUS | IEEE80211_CHAN_NO_HT40MINUS) - -/** - * struct ieee80211_channel - channel definition - * - * This structure describes a single channel for use - * with cfg80211. - * - * @center_freq: center frequency in MHz - * @hw_value: hardware-specific value for the channel - * @flags: channel flags from &enum ieee80211_channel_flags. - * @orig_flags: channel flags at registration time, used by regulatory - * code to support devices with additional restrictions - * @band: band this channel belongs to. - * @max_antenna_gain: maximum antenna gain in dBi - * @max_power: maximum transmission power (in dBm) - * @max_reg_power: maximum regulatory transmission power (in dBm) - * @beacon_found: helper to regulatory code to indicate when a beacon - * has been found on this channel.

The driver has to - * handle all the rest... - * - * The initial API also defines a specific handler in struct net_device - * to handle wireless statistics. - * - * The initial APIs served us well and has proven a reasonably good design. - * However, there is a few shortcommings : - * o No events, everything is a request to the driver. - * o Large ioctl function in driver with gigantic switch statement - * (i.e. spaghetti code). - * o Driver has to mess up with copy_to/from_user, and in many cases - * does it unproperly. Common mistakes are : - * * buffer overflows (no checks or off by one checks) - * * call copy_to/from_user with irq disabled - * o The user space interface is tied to ioctl because of the use - * copy_to/from_user. - * - * New driver API (2002 -> onward) : - * ------------------------------- - * The new driver API is just a bunch of standard functions (handlers), - * each handling a specific Wireless Extension. The driver just export - * the list of handler it supports, and those will be called apropriately. - * - * I tried to keep the main advantage of the previous API (simplicity, - * efficiency and light weight), and also I provide a good dose of backward - * compatibility (most structures are the same, driver can use both API - * simultaneously, ...). - * Hopefully, I've also addressed the shortcomming of the initial API. - * - * The advantage of the new API are : - * o Handling of Extensions in driver broken in small contained functions - * o Tighter checks of ioctl before calling the driver - * o Flexible commit strategy (at least, the start of it) - * o Backward compatibility (can be mixed with old API) - * o Driver doesn't have to worry about memory and user-space issues - * The last point is important for the following reasons : - * o You are now able to call the new driver API from any API you - * want (including from within other parts of the kernel). - * o Common mistakes are avoided (buffer overflow, user space copy - * with irq disabled and so on). - * - * The Drawback of the new API are : - * o bloat (especially kernel) - * o need to migrate existing drivers to new API - * My initial testing shows that the new API adds around 3kB to the kernel - * and save between 0 and 5kB from a typical driver. - * Also, as all structures and data types are unchanged, the migration is - * quite straightforward (but tedious). - * - * --- - * - * The new driver API is defined below in this file. User space should - * not be aware of what's happening down there... - * - * A new kernel wrapper is in charge of validating the IOCTLs and calling - * the appropriate driver handler. This is implemented in : - * # net/core/wireless.c - * - * The driver export the list of handlers in : - * # include/linux/netdevice.h (one place) - * - * The new driver API is available for WIRELESS_EXT >= 13. - * Good luck with migration to the new API ;-) - */ - -/* ---------------------- THE IMPLEMENTATION ---------------------- */ -/* - * Some of the choice I've made are pretty controversials. Defining an - * API is very much weighting compromises. This goes into some of the - * details and the thinking behind the implementation. - * - * Implementation goals : - * -------------------- - * The implementation goals were as follow : - * o Obvious : you should not need a PhD to understand what's happening, - * the benefit is easier maintenance. - * o Flexible : it should accommodate a wide variety of driver - * implementations and be as flexible as the old API. - * o Lean : it should be efficient memory wise to minimise the impact - * on kernel footprint. - * o Transparent to user space : the large number of user space - * applications that use Wireless Extensions should not need - * any modifications. - * - * Array of functions versus Struct of functions - * --------------------------------------------- - * 1) Having an array of functions allow the kernel code to access the - * handler in a single lookup, which is much more efficient (think hash - * table here). - * 2) The only drawback is that driver writer may put their handler in - * the wrong slot. This is trivial to test (I set the frequency, the - * bitrate changes). Once the handler is in the proper slot, it will be - * there forever, because the array is only extended at the end. - * 3) Backward/forward compatibility : adding new handler just require - * extending the array, so you can put newer driver in older kernel - * without having to patch the kernel code (and vice versa). - * - * All handler are of the same generic type - * ---------------------------------------- - * That's a feature !!! - * 1) Having a generic handler allow to have generic code, which is more - * efficient. If each of the handler was individually typed I would need - * to add a big switch in the kernel (== more bloat). This solution is - * more scalable, adding new Wireless Extensions doesn't add new code. - * 2) You can use the same handler in different slots of the array. For - * hardware, it may be more efficient or logical to handle multiple - * Wireless Extensions with a single function, and the API allow you to - * do that. (An example would be a single record on the card to control - * both bitrate and frequency, the handler would read the old record, - * modify it according to info->cmd and rewrite it). - * - * Functions prototype uses union iwreq_data - * ----------------------------------------- - * Some would have preferred functions defined this way : - * static int mydriver_ioctl_setrate(struct net_device *dev, - * long rate, int auto) - * 1) The kernel code doesn't "validate" the content of iwreq_data, and - * can't do it (different hardware may have different notion of what a - * valid frequency is), so we don't pretend that we do it. - * 2) The above form is not extendable. If I want to add a flag (for - * example to distinguish setting max rate and basic rate), I would - * break the prototype. Using iwreq_data is more flexible. - * 3) Also, the above form is not generic (see above). - * 4) I don't expect driver developper using the wrong field of the - * union (Doh !), so static typechecking doesn't add much value. - * 5) Lastly, you can skip the union by doing : - * static int mydriver_ioctl_setrate(struct net_device *dev, - * struct iw_request_info *info, - * struct iw_param *rrq, - * char *extra) - * And then adding the handler in the array like this : - * (iw_handler) mydriver_ioctl_setrate, // SIOCSIWRATE - * - * Using functions and not a registry - * ---------------------------------- - * Another implementation option would have been for every instance to - * define a registry (a struct containing all the Wireless Extensions) - * and only have a function to commit the registry to the hardware. - * 1) This approach can be emulated by the current code, but not - * vice versa. - * 2) Some drivers don't keep any configuration in the driver, for them - * adding such a registry would be a significant bloat. - * 3) The code to translate from Wireless Extension to native format is - * needed anyway, so it would not reduce significantely the amount of code. - * 4) The current approach only selectively translate Wireless Extensions - * to native format and only selectively set, whereas the registry approach - * would require to translate all WE and set all parameters for any single - * change. - * 5) For many Wireless Extensions, the GET operation return the current - * dynamic value, not the value that was set. - * - * This header is <net/iw_handler.h> - * --------------------------------- - * 1) This header is kernel space only and should not be exported to - * user space. Headers in "include/linux/" are exported, headers in - * "include/net/" are not. - * - * Mixed 32/64 bit issues - * ---------------------- - * The Wireless Extensions are designed to be 64 bit clean, by using only - * datatypes with explicit storage size. - * There are some issues related to kernel and user space using different - * memory model, and in particular 64bit kernel with 32bit user space. - * The problem is related to struct iw_point, that contains a pointer - * that *may* need to be translated. - * This is quite messy. The new API doesn't solve this problem (it can't), - * but is a step in the right direction : - * 1) Meta data about each ioctl is easily available, so we know what type - * of translation is needed. - * 2) The move of data between kernel and user space is only done in a single - * place in the kernel, so adding specific hooks in there is possible. - * 3) In the long term, it allows to move away from using ioctl as the - * user space API. - * - * So many comments and so few code - * -------------------------------- - * That's a feature. Comments won't bloat the resulting kernel binary. - */ - -/***************************** INCLUDES *****************************/ - -#include <linux/wireless.h> /* IOCTL user space API */ -#include <linux/if_ether.h> - -/***************************** VERSION *****************************/ -/* - * This constant is used to know which version of the driver API is - * available.

In that case, it will be told about the desired powersave mode - * with the %IEEE80211_CONF_PS flag depending on the association status. - * The hardware must take care of sending nullfunc frames when necessary, - * i.e. when entering and leaving powersave mode. The hardware is required - * to look at the AID in beacons and signal to the AP that it woke up when - * it finds traffic directed to it. - * - * %IEEE80211_CONF_PS flag enabled means that the powersave mode defined in - * IEEE 802.11-2007 section 11.2 is enabled. This is not to be confused - * with hardware wakeup and sleep states. Driver is responsible for waking - * up the hardware before issuing commands to the hardware and putting it - * back to sleep at appropriate times. - * - * When PS is enabled, hardware needs to wakeup for beacons and receive the - * buffered multicast/broadcast frames after the beacon. Also it must be - * possible to send frames and receive the acknowledment frame. - * - * Other hardware designs cannot send nullfunc frames by themselves and also - * need software support for parsing the TIM bitmap. This is also supported - * by mac80211 by combining the %IEEE80211_HW_SUPPORTS_PS and - * %IEEE80211_HW_PS_NULLFUNC_STACK flags. The hardware is of course still - * required to pass up beacons. The hardware is still required to handle - * waking up for multicast traffic; if it cannot the driver must handle that - * as best as it can, mac80211 is too slow to do that. - * - * Dynamic powersave is an extension to normal powersave in which the - * hardware stays awake for a user-specified period of time after sending a - * frame so that reply frames need not be buffered and therefore delayed to - * the next wakeup. It's compromise of getting good enough latency when - * there's data traffic and still saving significantly power in idle - * periods. - * - * Dynamic powersave is simply supported by mac80211 enabling and disabling - * PS based on traffic. Driver needs to only set %IEEE80211_HW_SUPPORTS_PS - * flag and mac80211 will handle everything automatically. Additionally, - * hardware having support for the dynamic PS feature may set the - * %IEEE80211_HW_SUPPORTS_DYNAMIC_PS flag to indicate that it can support - * dynamic PS mode itself. The driver needs to look at the - * @dynamic_ps_timeout hardware configuration value and use it that value - * whenever %IEEE80211_CONF_PS is set. In this case mac80211 will disable - * dynamic PS feature in stack and will just keep %IEEE80211_CONF_PS - * enabled whenever user has enabled powersave. - * - * Some hardware need to toggle a single shared antenna between WLAN and - * Bluetooth to facilitate co-existence. These types of hardware set - * limitations on the use of host controlled dynamic powersave whenever there - * is simultaneous WLAN and Bluetooth traffic. For these types of hardware, the - * driver may request temporarily going into full power save, in order to - * enable toggling the antenna between BT and WLAN. If the driver requests - * disabling dynamic powersave, the @dynamic_ps_timeout value will be - * temporarily set to zero until the driver re-enables dynamic powersave. - * - * Driver informs U-APSD client support by enabling - * %IEEE80211_HW_SUPPORTS_UAPSD flag. The mode is configured through the - * uapsd paramater in conf_tx() operation. Hardware needs to send the QoS - * Nullfunc frames and stay awake until the service period has ended. To - * utilize U-APSD, dynamic powersave is disabled for voip AC and all frames - * from that AC are transmitted with powersave enabled. - * - * Note: U-APSD client mode is not yet supported with - * %IEEE80211_HW_PS_NULLFUNC_STACK. - */ - -/** - * DOC: Beacon filter support - * - * Some hardware have beacon filter support to reduce host cpu wakeups - * which will reduce system power consumption. It usually works so that - * the firmware creates a checksum of the beacon but omits all constantly - * changing elements (TSF, TIM etc). Whenever the checksum changes the - * beacon is forwarded to the host, otherwise it will be just dropped.

This can consist in notifying the host when - * the RSSI changes significantly or when it drops below or rises above - * configurable thresholds. In the future these thresholds will also be - * configured by mac80211 (which gets them from userspace) to implement - * them as the roaming algorithm requires. - * - * If the hardware cannot implement this, the driver should ask it to - * periodically pass beacon frames to the host so that software can do the - * signal strength threshold checking. - */ - -/** - * DOC: Spatial multiplexing power save - * - * SMPS (Spatial multiplexing power save) is a mechanism to conserve - * power in an 802.11n implementation.

However, for best CPU usage and power consumption, - * having as few frames as possible percolate through the stack is - * desirable. Hence, the hardware should filter as much as possible. - * - * To achieve this, mac80211 uses filter flags (see below) to tell - * the driver's configure_filter() function which frames should be - * passed to mac80211 and which should be filtered out. - * - * Before configure_filter() is invoked, the prepare_multicast() - * callback is invoked with the parameters @mc_count and @mc_list - * for the combined multicast address list of all virtual interfaces. - * It's use is optional, and it returns a u64 that is passed to - * configure_filter(). Additionally, configure_filter() has the - * arguments @changed_flags telling which flags were changed and - * @total_flags with the new flag states. - * - * If your device has no multicast address filters your driver will - * need to check both the %FIF_ALLMULTI flag and the @mc_count - * parameter to see whether multicast frames should be accepted - * or dropped. - * - * All unsupported flags in @total_flags must be cleared. - * Hardware does not support a flag if it is incapable of _passing_ - * the frame to the stack. Otherwise the driver must ignore - * the flag, but not clear it. - * You must _only_ clear the flag (announce no support for the - * flag to mac80211) if you are not able to pass the packet type - * to the stack (so the hardware always filters it). - * So for example, you should clear @FIF_CONTROL, if your hardware - * always filters control frames. If your hardware always passes - * control frames to the kernel and is incapable of filtering them, - * you do _not_ clear the @FIF_CONTROL flag. - * This rule applies to all other FIF flags as well. - */ - -/** - * DOC: AP support for powersaving clients - * - * In order to implement AP and P2P GO modes, mac80211 has support for - * client powersaving, both "legacy" PS (PS-Poll/null data) and uAPSD. - * There currently is no support for sAPSD. - * - * There is one assumption that mac80211 makes, namely that a client - * will not poll with PS-Poll and trigger with uAPSD at the same time. - * Both are supported, and both can be used by the same client, but - * they can't be used concurrently by the same client. This simplifies - * the driver code. - * - * The first thing to keep in mind is that there is a flag for complete - * driver implementation: %IEEE80211_HW_AP_LINK_PS. If this flag is set, - * mac80211 expects the driver to handle most of the state machine for - * powersaving clients and will ignore the PM bit in incoming frames. - * Drivers then use ieee80211_sta_ps_transition() to inform mac80211 of - * stations' powersave transitions. In this mode, mac80211 also doesn't - * handle PS-Poll/uAPSD. - * - * In the mode without %IEEE80211_HW_AP_LINK_PS, mac80211 will check the - * PM bit in incoming frames for client powersave transitions. When a - * station goes to sleep, we will stop transmitting to it. There is, - * however, a race condition: a station might go to sleep while there is - * data buffered on hardware queues. If the device has support for this - * it will reject frames, and the driver should give the frames back to - * mac80211 with the %IEEE80211_TX_STAT_TX_FILTERED flag set which will - * cause mac80211 to retry the frame when the station wakes up. The - * driver is also notified of powersave transitions by calling its - * @sta_notify callback. - * - * When the station is asleep, it has three choices: it can wake up, - * it can PS-Poll, or it can possibly start a uAPSD service period. - * Waking up is implemented by simply transmitting all buffered (and - * filtered) frames to the station. This is the easiest case. When - * the station sends a PS-Poll or a uAPSD trigger frame, mac80211 - * will inform the driver of this with the @allow_buffered_frames - * callback; this callback is optional. mac80211 will then transmit - * the frames as usual and set the %IEEE80211_TX_CTL_NO_PS_BUFFER - * on each frame. The last frame in the service period (or the only - * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to - * indicate that it ends the service period; as this frame must have - * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS. - * When TX status is reported for this frame, the service period is - * marked has having ended and a new one can be started by the peer. - * - * Additionally, non-bufferable MMPDUs can also be transmitted by - * mac80211 with the %IEEE80211_TX_CTL_NO_PS_BUFFER set in them. - * - * Another race condition can happen on some devices like iwlwifi - * when there are frames queued for the station and it wakes up - * or polls; the frames that are already queued could end up being - * transmitted first instead, causing reordering and/or wrong - * processing of the EOSP. The cause is that allowing frames to be - * transmitted to a certain station is out-of-band communication to - * the device. To allow this problem to be solved, the driver can - * call ieee80211_sta_block_awake() if frames are buffered when it - * is notified that the station went to sleep. When all these frames - * have been filtered (see above), it must call the function again - * to indicate that the station is no longer blocked. - * - * If the driver buffers frames in the driver for aggregation in any - * way, it must use the ieee80211_sta_set_buffered() call when it is - * notified of the station going to sleep to inform mac80211 of any - * TIDs that have frames buffered. Note that when a station wakes up - * this information is reset (hence the requirement to call it when - * informed of the station going to sleep). Then, when a service - * period starts for any reason, @release_buffered_frames is called - * with the number of frames to be released and which TIDs they are - * to come from. In this case, the driver is responsible for setting - * the EOSP (for uAPSD) and MORE_DATA bits in the released frames, - * to help the @more_data paramter is passed to tell the driver if - * there is more data on other TIDs -- the TIDs to release frames - * from are ignored since mac80211 doesn't know how many frames the - * buffers for those TIDs contain. - * - * If the driver also implement GO mode, where absence periods may - * shorten service periods (or abort PS-Poll responses), it must - * filter those response frames except in the case of frames that - * are buffered in the driver -- those must remain buffered to avoid - * reordering. Because it is possible that no frames are released - * in this case, the driver must call ieee80211_sta_eosp_irqsafe() - * to indicate to mac80211 that the service period ended anyway. - * - * Finally, if frames from multiple TIDs are released from mac80211 - * but the driver might reorder them, it must clear & set the flags - * appropriately (only the last frame may have %IEEE80211_TX_STATUS_EOSP) - * and also take care of the EOSP and MORE_DATA bits in the frame. - * The driver may also use ieee80211_sta_eosp_irqsafe() in this case. - */ - -/** - * enum ieee80211_filter_flags - hardware filter flags - * - * These flags determine what the filter in hardware should be - * programmed to let through and what should not be passed to the - * stack.

If the @more_data parameter is %true, then of course the - * more-data bit must always be set. - * The @tids parameter tells the driver which TIDs to release frames - * from, for PS-poll it will always have only a single bit set. - * In the case this is used for a PS-poll initiated release, the - * @num_frames parameter will always be 1 so code can be shared. In - * this case the driver must also set %IEEE80211_TX_STATUS_EOSP flag - * on the TX status (and must report TX status) so that the PS-poll - * period is properly ended. This is used to avoid sending multiple - * responses for a retried PS-poll frame. - * In the case this is used for uAPSD, the @num_frames parameter may be - * bigger than one, but the driver may send fewer frames (it must send - * at least one, however). In this case it is also responsible for - * setting the EOSP flag in the QoS header of the frames. Also, when the - * service period ends, the driver must set %IEEE80211_TX_STATUS_EOSP - * on the last frame in the SP. Alternatively, it may call the function - * ieee80211_sta_eosp_irqsafe() to inform mac80211 of the end of the SP. - * This callback must be atomic. - * @allow_buffered_frames: Prepare device to allow the given number of frames - * to go out to the given station. The frames will be sent by mac80211 - * via the usual TX path after this call. The TX information for frames - * released will also have the %IEEE80211_TX_CTL_NO_PS_BUFFER flag set - * and the last one will also have %IEEE80211_TX_STATUS_EOSP set. In case - * frames from multiple TIDs are released and the driver might reorder - * them between the TIDs, it must set the %IEEE80211_TX_STATUS_EOSP flag - * on the last frame and clear it on all others and also handle the EOSP - * bit in the QoS header correctly. Alternatively, it can also call the - * ieee80211_sta_eosp_irqsafe() function. - * The @tids parameter is a bitmap and tells the driver which TIDs the - * frames will be on; it will at most have two bits set. - * This callback must be atomic. - */ -struct ieee80211_ops { - void (*tx)(struct ieee80211_hw *hw, struct sk_buff *skb);

This API is designed to be growable in - * order to address this problem. - * - * USAGE - * - * Embed a `struct wimax_dev` at the beginning of the the device's - * private structure, initialize and register it. For details, see - * `struct wimax_dev`s documentation. - * - * Once this is done, wimax-tools's libwimaxll can be used to - * communicate with the driver from user space. You user space - * application does not have to forcibily use libwimaxll and can talk - * the generic netlink protocol directly if desired. - * - * Remember this is a very low level API that will to provide all of - * WiMAX features. Other daemons and services running in user space - * are the expected clients of it. They offer a higher level API that - * applications should use (an example of this is the Intel's WiMAX - * Network Service for the i2400m). - * - * DESIGN - * - * Although not set on final stone, this very basic interface is - * mostly completed. Remember this is meant to grow as new common - * operations are decided upon. New operations will be added to the - * interface, intent being on keeping backwards compatibility as much - * as possible. - * - * This layer implements a set of calls to control a WiMAX device, - * exposing a frontend to the rest of the kernel and user space (via - * generic netlink) and a backend implementation in the driver through - * function pointers. - * - * WiMAX devices have a state, and a kernel-only API allows the - * drivers to manipulate that state. State transitions are atomic, and - * only some of them are allowed (see `enum wimax_st`). - * - * Most API calls will set the state automatically; in most cases - * drivers have to only report state changes due to external - * conditions. - * - * All API operations are 'atomic', serialized through a mutex in the - * `struct wimax_dev`. - * - * EXPORTING TO USER SPACE THROUGH GENERIC NETLINK - * - * The API is exported to user space using generic netlink (other - * methods can be added as needed). - * - * There is a Generic Netlink Family named "WiMAX", where interfaces - * supporting the WiMAX interface receive commands and broadcast their - * signals over a multicast group named "msg". - * - * Mapping to the source/destination interface is done by an interface - * index attribute. - * - * For user-to-kernel traffic (commands) we use a function call - * marshalling mechanism, where a message X with attributes A, B, C - * sent from user space to kernel space means executing the WiMAX API - * call wimax_X(A, B, C), sending the results back as a message. - * - * Kernel-to-user (notifications or signals) communication is sent - * over multicast groups. This allows to have multiple applications - * monitoring them. - * - * Each command/signal gets assigned it's own attribute policy. This - * way the validator will verify that all the attributes in there are - * only the ones that should be for each command/signal. Thing of an - * attribute mapping to a type+argumentname for each command/signal. - * - * If we had a single policy for *all* commands/signals, after running - * the validator we'd have to check "does this attribute belong in - * here"? for each one. It can be done manually, but it's just easier - * to have the validator do that job with multiple policies. As well, - * it makes it easier to later expand each command/signal signature - * without affecting others and keeping the namespace more or less - * sane. Not that it is too complicated, but it makes it even easier. - * - * No state information is maintained in the kernel for each user - * space connection (the connection is stateless). - * - * TESTING FOR THE INTERFACE AND VERSIONING - * - * If network interface X is a WiMAX device, there will be a Generic - * Netlink family named "WiMAX X" and the device will present a - * "wimax" directory in it's network sysfs directory - * (/sys/class/net/DEVICE/wimax) [used by HAL]. - * - * The inexistence of any of these means the device does not support - * this WiMAX API. - * - * By querying the generic netlink controller, versioning information - * and the multicast groups available can be found. Applications using - * the interface can either rely on that or use the generic netlink - * controller to figure out which generic netlink commands/signals are - * supported. - * - * NOTE: this versioning is a last resort to avoid hard - * incompatibilities. It is the intention of the design of this - * stack not to introduce backward incompatible changes. - * - * The version code has to fit in one byte (restrictions imposed by - * generic netlink); we use `version / 10` for the major version and - * `version % 10` for the minor. This gives 9 minors for each major - * and 25 majors. - * - * The version change protocol is as follow: - * - * - Major versions: needs to be increased if an existing message/API - * call is changed or removed. Doesn't need to be changed if a new - * message is added. - * - * - Minor version: needs to be increased if new messages/API calls are - * being added or some other consideration that doesn't impact the - * user-kernel interface too much (like some kind of bug fix) and - * that is kind of left up in the air to common sense. - * - * User space code should not try to work if the major version it was - * compiled for differs from what the kernel offers. As well, if the - * minor version of the kernel interface is lower than the one user - * space is expecting (the one it was compiled for), the kernel - * might be missing API calls; user space shall be ready to handle - * said condition. Use the generic netlink controller operations to - * find which ones are supported and which not. - * - * libwimaxll:wimaxll_open() takes care of checking versions. - * - * THE OPERATIONS: - * - * Each operation is defined in its on file (drivers/net/wimax/op-*.c) - * for clarity. The parts needed for an operation are: - * - * - a function pointer in `struct wimax_dev`: optional, as the - * operation might be implemented by the stack and not by the - * driver. - * - * All function pointers are named wimax_dev->op_*(), and drivers - * must implement them except where noted otherwise. - * - * - When exported to user space, a `struct nla_policy` to define the - * attributes of the generic netlink command and a `struct genl_ops` - * to define the operation. - * - * All the declarations for the operation codes (WIMAX_GNL_OP_<NAME>) - * and generic netlink attributes (WIMAX_GNL_<NAME>_*) are declared in - * include/linux/wimax.h; this file is intended to be cloned by user - * space to gain access to those declarations. - * - * A few caveats to remember: - * - * - Need to define attribute numbers starting in 1; otherwise it - * fails. - * - * - the `struct genl_family` requires a maximum attribute id; when - * defining the `struct nla_policy` for each message, it has to have - * an array size of WIMAX_GNL_ATTR_MAX+1. - * - * The op_*() function pointers will not be called if the wimax_dev is - * in a state <= %WIMAX_ST_UNINITIALIZED. The exception is: - * - * - op_reset: can be called at any time after wimax_dev_add() has - * been called. - * - * THE PIPE INTERFACE: - * - * This interface is kept intentionally simple. The driver can send - * and receive free-form messages to/from user space through a - * pipe. See drivers/net/wimax/op-msg.c for details. - * - * The kernel-to-user messages are sent with - * wimax_msg(). user-to-kernel messages are delivered via - * wimax_dev->op_msg_from_user(). - * - * RFKILL: - * - * RFKILL support is built into the wimax_dev layer; the driver just - * needs to call wimax_report_rfkill_{hw,sw}() to inform of changes in - * the hardware or software RF kill switches. When the stack wants to - * turn the radio off, it will call wimax_dev->op_rfkill_sw_toggle(), - * which the driver implements. - * - * User space can set the software RF Kill switch by calling - * wimax_rfkill(). - * - * The code for now only supports devices that don't require polling; - * If the device needs to be polled, create a self-rearming delayed - * work struct for polling or look into adding polled support to the - * WiMAX stack. - * - * When initializing the hardware (_probe), after calling - * wimax_dev_add(), query the device for it's RF Kill switches status - * and feed it back to the WiMAX stack using - * wimax_report_rfkill_{hw,sw}(). If any switch is missing, always - * report it as ON. - * - * NOTE: the wimax stack uses an inverted terminology to that of the - * RFKILL subsystem: - * - * - ON: radio is ON, RFKILL is DISABLED or OFF. - * - OFF: radio is OFF, RFKILL is ENABLED or ON. - * - * MISCELLANEOUS OPS: - * - * wimax_reset() can be used to reset the device to power on state; by - * default it issues a warm reset that maintains the same device - * node. If that is not possible, it falls back to a cold reset - * (device reconnect). The driver implements the backend to this - * through wimax_dev->op_reset(). - */ - -#ifndef __NET__WIMAX_H__ -#define __NET__WIMAX_H__ - -#include <linux/wimax.h> -#include <net/genetlink.h> -#include <linux/netdevice.h> - -struct net_device; -struct genl_info; -struct wimax_dev; - -/** - * struct wimax_dev - Generic WiMAX device - * - * @net_dev: [fill] Pointer to the &struct net_device this WiMAX - * device implements. - * - * @op_msg_from_user: [fill] Driver-specific operation to - * handle a raw message from user space to the driver.

Move the device to %WIMAX_ST_UNINITIALIZED. This is needed so - * some API calls that shouldn't work until the device is ready - * can be blocked. - * - * b. Initialize the device.

Once - * wimax_dev_add() is called, the driver can get called on the - * wimax_dev->op_* function pointers - * - * CONCURRENCY: - * - * The stack provides a mutex for each device that will disallow API - * calls happening concurrently; thus, op calls into the driver - * through the wimax_dev->op*() function pointers will always be - * serialized and *never* concurrent. - * - * For locking, take wimax_dev->mutex is taken; (most) operations in - * the API have to check for wimax_dev_is_ready() to return 0 before - * continuing (this is done internally). - * - * REFERENCE COUNTING: - * - * The WiMAX device is reference counted by the associated network - * device.
